To any trained eye, the two released photos suggest illness. And if one was to be unkind, it almost looks like he may have just thrown on clothes for the camera, perhaps even borrowed these clothes from his new Chinese friends.
Certainly, one can see that the first picture could even be in a private hospital room - see fruit, dinner-for-one place set. And why are his hands on hips in both photos? Could it be he hasn’t got a belt to hand and needs to stop trousers from falling down? Having been in a hospital patients gown?
It would certainly be strange for a Prime Minister and military commander to meet with officials from the China Railway First Company without tucking in shirt, no ties-all-round.
